Within the framework of the research project, the restart phase following a tool change on a forming machine was analyzed, evaluated, and systematized, and the information gained was stored in the form of a catalogue of measures. The information flow is secured in the form of graphics (flow diagrams) and text. Because avoiding production errors as well as preventive measures are given special priority, an additional investigation was carried out on the apperance of imminent errors. These measures were accompanied by measuring technology investigations of setting and process parameters. With the goal of improved interpretation of the apperance of errors and the reliable allocation of the causes of errors, the use of the temperature filed as an "accompanying integral measuring variable" was investigated.
